SOUTH BRUNSWICK — A South Brunswick woman was killed and two men injured this morning in a two-vehicle accident at the intersection of Route 522 and Ridge Road, police said.

Township police said Elsie Casey, 67, was driving a 2001 Mercury Sable on Ridge Road when she entered the intersection at 10:15 a.m. and was struck by a 2009 Toyota Rav 4 driven by Harry Eichler, 69, who was headed west on Route 522.

Authorities said Eichler's vehicle came to rest on the concrete divider while Casey's car was pushed into the westbound lanes of Route 522.

Police said Casey had to be extricated from her car. Casey, Eichler and Eichler's passenger, John Blech, 59, were taken to Robert Wood Johnson University Hospital in New Brunswick, where Casey was pronounced dead at 11:17 a.m.

Eichler is under observation in the emergency room and Blech is in serious condition, police said. Both men are from South Brunswick.

Police said preliminary indications are that Casey went through a red traffic signal, resulting in the crash. The road was closed for about 90 minutes during the investigation.

Authorities said this is the third fatal car crash in South Brunswick this year.
